Sigmatherm INSTALLATION INSTRUCTIONS 1" & 1-1/4" Thermostatic Mixing Valve Single Exit For use with 1" and 1-1/4" Copper Pipe Only 0 SHUT-OFFS PLASTIC HOUSING BUSHING SQUARE TUBE THERMO POINTER ASSEMBLY THREADED TUBE NOTE: NEVER CUT INSIDE THREAD END COVER PLATE SIGMA ESCUTCHEON GREY PLASTIC OR OPTIONAL SOLID BRASS DIAL SIGMA HANDLE This valve is single exit only. (Top Exit) Bottom outlet is for draining valve only and is supplied with a plug. Installation Please Note: The first step in installation, removal of the cartridge, has already been done at the factory. The cartridge has been packaged separately from the valve body to prevent clogging the cartridge during installation. Install the cartridge only when the hot and cold water lines are flushed and fully operational. The water heater must be working or the unit will not work. We recommend the installation of in-line plumber supplied shut-off valves close to the hot and cold inlets. Please remember the cartridge should be removed and cleaned annually for optimum useful life of the system. The following parts may be ordered to extend stem: 4-1/2 Threaded Tube (Part #18.30.088) 5 Square Tube (Part #18.30.087) Cover Page 1 of 9
Connections Installation Instructions For 1" and 1-1/4" Valves Assembly USE TOP EXIT ONLY SIZE COPPER PIPE TO MATCH VALVE PORTS Plug on bottom of valve for draining body in case of severe cold temperature. Reverse steps performed when removing the cartridge to re-install the cartridge (see p. 3 for diagram). Assemble the cartridge (2), the cover (3) with its screws, fit the threaded tube (9), and screw home. Place the plate (7) and the dial (11) onto the assembly. Make a cutting mark 3/16" from the dial face. Remove the tube, cut it, and debur the cut carefully. Screw the tube home again. -Important- Connect the hot water to the side with the red mark and the cold water to the side with the blue mark. The plastic housing should act as a depth guide for the plumber. Install the valve so the housing extends beyond the finish wall 1/2". Cut the plastic housing flush with the FINISH wall. The plastic housing is to remain with the valve body always for maintenance reasons. Valve is shipped with standard extensions. Flushing Lines Flush the supply pipes completely and carefully by closing the body with the cover and its screws without the cartridge. Keep foreign matter OUT of the cartridge. - Screw the bushing onto the threaded tube. Slide the square tube into the bushing and drive it completely into the control spindle. - Make a cutting mark on the square tube flush with the bushing. Remove the square tube, cut it, and debur carefully. Replace the tube into the bushing and push it all the way into its recess. Page 2
Temperature Calibration Cartridge Removal Guide (Future reference ONLY) Let the water flow and bring this to a mean temperature by actuating the bushing (12). Note this temperature. Place the pointer assembly (6) on the bushing and position the red index opposite the graduation corresponding to the temperature noted. Tighten up the cap setscrew and fit the knob (4) again. When in use, if a water above 104 o F is desired, press the red index and turn the knob to the left. Maintenance Filter Cleaning If the cartridge is installed prior to flushing the lines you may inadvertantly clog the filters. Dirty filters may lead to a reduction in the flow rate. It is then necessary to clean them with a brush after removing the cartridge (2) from the body of the appliance (see "Cartridge Removal Guide). Brush the outsides of the filters ONLY. NEVER undo the brass screws, as doing so will VOID THE WARRANTY. D. Cleaning the Cartridge If the cartridge is installed prior to flushing the lines you may inadvertantly clog the filters. It will be necessary to remove the cartridge from the mixing valve - never take the cartridge apart or you will void all warranties. Simply soak the entire cartridge in plain vinegar for 1 to 3 hours and reinstall the valve. 90% of the time the valve will then work normally. See Operating Incidents for further details. Emptying in case of Frost When the appliance is exposed to freezing conditions it is ESSENTIAL to empty it: - either by turning on a tap at the bottom outlet - or by opening the cover (3) of the appliance.

GENERAL THERMOSTATIC INFORMATION FOR HOME OWNER Please read the complete Thermostatic instructions and cautions contained in this booklet before attempting to install the Thermostatic Valve System. Please be sure the Homeowner is provided the booklet for future reference for regular maintenance. FEATURES: The Eurotherm brand of Thermostatic valves have been in use worldwide for over fifty years. Complete serviceability from front of all units. Sizes vary from 1/2-3/4-1, 1-1/4, 1-1/2. and 2 for residential use. Cartridge is constructed using Bi-Metal Strip and Built-in Check Valves. The Bi-Metallic cartridge delivers the highest flow rate in the industry today. The Bi-Metallic cartridge has the fastest response time plus + (or) minus -1 second, and 1 Fahrenheit when fluctuation in supply pressure occurs. Extension kits are available through your dealer at an extra charge. Keep in mind that the distance the shower head or other exit is from the valve will depend on how fast you feel the instantaneous correction in the temperature. Uniform dials and push-button over-rides are interchangeable on all sizes of valves. Page 4
FAILURE TO FOLLOW INSTRUCTIONS MAY CAUSE DAMAGE OR IMPROPER OPERATION AND VOID THE WARRANTY. 1. Flush all rough-in piping thoroughly to remove sediment, flux and other debris. 2. Hot and cold inlets are clearly marked. DO NOT REVERSE CONNECTIONS, THE UNIT WILL NOT WORK CORRECTLY. 3. DO NOT USE DIRECT HEAT, OR ANY TORCH ON ROUGH VALVES. 4. If unit comes with a black or gray plastic outer ring -- read directions and be sure you keep above ring installed even after the trim is installed. 5. Minimum and maximum finished wall tolerances are clearly marked. (SEE EXPLODED VIEW OF VALVE) 6. It is extremely important that the rough mixing chamber be free of all debris before installation of the thermostatic cartridge. Read all instructions on boxes, valves and cartridges. 7. Under no circumstances should the thermostat cartridge be dismantled. Doing so will void any warranty and generally make the cartridge inoperable. MAINTENANCE The Bi-Metallic strip cartridge has two filter screens and a simple cleaning with a toothbrush will remove surface debris. Soaking the cartridge in a 50/50 solution of clear household vinegar and water will remove lime scale, and lime deposits caused from your water. Regular cleaning each year will extend the life of the cartridge. Never use a screwdriver on any thermostatic cartridge. Never take a thermostatic cartridge apart as you will damage this precise instrument. Call your dealer or the factory for answers to your questions. Page 5
Sigmatherm Technical Information The Sigmatherm Thermostatic Valve is designed to operate at water pressures as low as 14 psi and as high as 140 psi. If you have lower or higher pressure please consult the factory representative for suggestions or solutions. 1/2", 3/4", and 1" units are most commonly used for the deluxe shower, suite, or residential bath. These units are available in any of our handle and finish trims. For more details contact your sales representative. 1-1/4", 1-1/2", and 2" units do not come with decorative trim, as these valves are very large and require easy access to install and use. Call for further details. Important: All main lines must be the same size or larger than the supplied valve or the flow rates will not work. Therefore, if you use a 1-1/4" valve your water system should be based on a minimum 1-1/4" line--absolutely no smaller restriction should be allowed. Water Supply Sigmatherm valves can be supplied from any hot water production system, even by instantaneous domestic production, as far as the generator is capable of supplying very small quantities of hot water (about 0.8 gal/min). - Maximum working pressure 145 PSI - Minimum working pressure 14 PSI - Recommended working pressure 29 to 58 PSI - Maximum test pressure 224 PSI - Maximum hot water temperature 185 F Options 'Reverse' cartridges are available to correct improper installation (this special order is an extra charge and takes 12 weeks for delivery). Shut-Off Valves The mixer itself determines the proportions of hot and cold water required for the mixture. The mixer however regulates the temperature only and not the output; one shut-off valve (or more) must therefore be provided at the outlet(s) to control water flow. Non-Return Valves and Filters Non-return valves are incorporated into the cartridge. Eurotherm incorporates easily accessible stainless steel filters at the inlets of the cartridge. However, in order to access the cartridge, we recommend the installation of in-line plumber supplied shut-off valves close to the hot and cold inlets. Please remember the cartridge should be removed and cleaned annually for optimum useful life of the system. Page 6

CONSUMER WARNING CALIFORNIA PROPOSTION 65 WARNING Among other chemicals known to cause harm, this faucet contains lead, a chemical known to the State of California to cause birth defects or other reproductive harm. All faucets and products made of leaded brass alloys, even those that comply with U.S. Environmental Protection Agency regulations, contribute small amounts of lead to water that is allowed to stand in contact with the brass. This faucet complies with all E.P.A. regulations regarding the amount of lead used in plumbing brass and solder. The amount of lead contributed by any faucet is highest when the faucet is new. The following steps will reduce potential for exposure to lead from faucets and other parts of the plumbing system: Always run the water for a few seconds prior to use for drinking or cooking. Use only cold water for drinking or cooking. If you wish to flush the entire plumbing system of water that has been standing in the pipes or other fittings, run the cold water until the temperature of the water drops, indicating water coming from the outside main. If you are concerned about lead in your water, have your water tested. Page 9
